There's no empirical evidence that MJ sexually abused any children. He was also acquitted. Why does this rumor persist? Because some guy who has changed his story multiple times decided after MJ died that he was abused, despite previous evidence that he wasn't abused and that his parents tried to blackmail MJ?
I mean it's a little quip so you probably didn't think much of it. But he suffered enough while alive, is it really necessary to continue to assassinate his character despite him being dead and acquitted?
I think you need to take the thought of "network" completely out of your mind. This protocol is specifically regarding devices such as air tags, which don't have any network capability themselves but rely on "connecting" to Bluetooth of the manufacturers models. The phones themselves are what gives tracking information back, based on GPS of the phone that was in proximity of the tracker.
The question that Google/Apple have is, how can we make sure people aren't unknowingly being tracked by someone putting a physical tracker in say, your car. THAT'S the "protocol" part. A protocol is just an agreement on how a technology is going to be implemented. If your own tracker is following you that's fine, the MAC address will keep changing. If someone else's air tag is following you, your phone will know this tracker has been near you for some time, and will tell you.
